It's not taboo, just that RB3 favored the solo score freak and real instrument learner types who delight in chasing away the story/character players.
Yeah - that was my first Guitar Hero game. My first music game was Frets on Fire, then Rock Band 1. I wanted more music games, so I got GH3. Obviously I prefer RB (but I own every GH game). And I liked her look in GH3 - first exposure to the character and such.
4 singles - 2 I'll get (Queensryche and one Staind).
